Abstract

Sistema de control de cambios para una transmision de cambios de potencia basado en deslizamiento de embrague. Un método para controlar, en respuesta a uncomando de cambio, un cambio comandado de una transmision de cambios de potencia de un vehículo impulsado a motor incluye el monitoreo del componente detransmision de velocidades seleccionado de acuerdo con el cambio comandado y el monitoreo de la relacion de velocidad del mismo. Si la seccion de entrada seacelera durante el cambio comandado, l os embragues de velocidad son intercambiados y luego los embragues de salida son intercambiados cuando la relacion develocidad monitoreada coincide con una relacion de velocidad. También la velocidad de entrada de un eje de entrada de la transmisiom es monitoreado, y lapresion del embrague de salida saliente es controlada para limitar la desaceleracion de la velocidad del eje de entrada a los límites deseados. Si la seccionde entrada desacelera durante el cambio comandado, los embragues de salid a son intercambiados, y luego los embragues de velocidad son intercambiados cuando unarelacion de velocidad monitoreada coincide con una relacion de velocidad almacenada. Si un cambio particular requiere el intercambio de solamente embragues develoci dad, entonces se monitorea una relacion de velocidad para el par de embragues de velocidad a ser intercambiados. Si la seccion de entrada se acelera odesacelera durante el cambio comandado, el par de embragues de velocidad se intercambia, y la relaci on de velocidad monitoreada se compara con un valor derelacion de velocidad almacenada predeterminada para determinar cuando se completa el intercambio de los embragues de velocidad, y después que los embragues develocidad son intercambiados, uno de los embragues de salida es completamente presurizado para completar el cambio.Change control system for a transmission of power changes based on clutch slip. One method of controlling, in response to a changeover command, a commanded change of a transmission of power changes of a motor driven vehicle includes monitoring of the selected gear transmission component in accordance with the commanded change and monitoring of the ratio of speed of it. If the input section is accelerated during the commanded change, the speed clutches are exchanged and then the output clutches are exchanged when the monitored speed ratio coincides with a speed ratio. Also the input speed of an input shaft of the transmission is monitored, and the pressure of the outgoing output clutch is controlled to limit the deceleration of the input shaft speed to the desired limits. If the input section slows down during the commanded change, the output clutches are exchanged, and then the speed clutches are exchanged when a monitored speed ratio matches a stored speed ratio. If a particular change requires the exchange of only clutches, then a speed ratio is monitored for the pair of speed clutches to be exchanged. If the input section is accelerated or decelerated during the commanded change, the pair of speed clutches is exchanged, and the monitored speed ratio is compared with a predetermined stored velocity ratio value to determine when the exchange of clutches is completed. speed, and after the speed clutches are exchanged, one of the output clutches is completely pressurized to complete the change.
